Overview

What the Overledger Zapier integration does

The integration links your Overledger account to Zapier, a tool that runs automations between apps without code. Each automation is a Zap: one trigger, the event that starts it, then one or more actions, the steps that do the work. Here the triggers watch Ethereum-based accounts and smart contracts, and the actions read, prepare and sign on those same networks.

Three outcomes come up most. A transaction alert: New Account Event starts the Zap when a transaction goes to or from a watched address, and the next step tells the right person on your team. A contract reading: New Contract Event fires on a contract event, then Read a Smart Contract Function fetches the value behind it. A signing chain on test networks: Prepare a Smart Contract Transaction, then Sign a Transaction, the second step fed by the first.

What Zapier does not do here matters just as much. There is no search step, so a Zap cannot look up an existing Overledger record before acting. Signing only runs on the Sandbox instance, which means test networks. Only Ethereum-based blockchains are offered. And nothing that happened before the Zap went live gets picked up. If you are still weighing the tool itself, read the Zapier review. The same app also has an Overledger Make integration.

Vocabulary

Zapier words, in plain English

Eight terms carry the rest of this page. Each one is explained once, here.

Zap
The automation you build in Zapier: one trigger, then one or more actions that run each time the trigger event happens.
Trigger
The event in an app that starts the Zap. Once the Zap is on, Zapier waits for it: here, an Overledger account or contract event.
Action
What the Zap does after it starts: the step that reads, prepares or sends something for you, like reading a contract function.
Task
The unit Zapier bills. One task is one action your Zap completes successfully, and your plan counts exactly those.
Instant trigger
A trigger the app reports itself: it calls Zapier the moment the event happens, so nothing waits for a check. Both Overledger triggers work this way.
Polling trigger
A trigger Zapier checks on a timer, asking the app for new items at a fixed interval. Overledger has none, other apps in your Zaps may.
Filter
A step that lets the Zap go on only when what arrived meets the condition you set, and stops it otherwise.
Connection
Your Overledger account linked to Zapier once, then reused by every step of every Zap that uses Overledger.
Cost

What an Overledger Zap really costs

On Zapier you pay in tasks, not in triggers. Neither Overledger trigger costs anything, however often a watched account or contract moves. Each action that completes successfully counts as one task.

  • Trigger firing0 tasks
  • Successful action1 task (a few actions take more)
  • Failed action0 tasks
  • Free plan100 tasks a month, two-step Zaps
  • OverledgerNot premium, works on the free plan

An action that fails is not counted against your plan. The free plan gives 100 tasks a month and Zaps of two steps only: one trigger, one action. Add a second action or a filter and the Zap turns multi-step, which needs a paid plan. Overledger is not a premium app, so it works from the free plan. The interval grid below only concerns polling triggers; both Overledger triggers are instant and skip it.

Connect

Connect Overledger to Zapier in 3 steps

  1. 01

    Open Apps and add a connection

    In your Zapier account, open the Apps page and click + Add connection. You need an Overledger account first, plus access to any account or contract you do not own and want the Zap to touch.

  2. 02

    Find Overledger in the dialog

    Type Overledger in the search box of the dialog, pick it from the results, then click Add connection. A new tab opens on the Overledger side to finish the job.

  3. 03

    Sign in and grant access

    Sign in to Overledger in that tab and grant Zapier access to the account. The connection is saved, and every Overledger step you add later reuses it without asking again.

First Zap

Your first Overledger Zap, step by step

GoalRead a contract value each time a watched smart contract emits an event, but only for the events you care about.

  1. 01

    Pick the trigger

    Create a Zap, choose Overledger as the app that starts it and New Contract Event as the event. Set the instance, the technology and the contract address to watch.

  2. 02

    Test the trigger

    Run the trigger test. Zapier brings back the three most recent items of the connected account, so you map the next steps on a real event, not a guess.

  3. 03

    Add the filter

    Click the plus icon, add Filter, then set the field to look at, the rule and the value. Match the rule type to the data: a text rule only works on text.

  4. 04

    Add the reading

    Add Overledger again with Read a Smart Contract Function. Enter the contract address, the function name and the return types, then test the step and read what came back.

  5. 05

    Publish

    Click Publish to switch the Zap on. With its filter it is a multi-step Zap, so it needs a paid plan. Drop the filter and it fits the free plan.

Triggers

The 2 Overledger triggers

2 events start a Zap when something happens in Overledger, and 2 of them are instant: the app calls Zapier straight away, whatever your plan.

1

New Account Event

Instant trigger

In Zapier“Triggers when a transaction has been sent to or from an account.”

This trigger starts your Zap each time a transaction is sent to or from one blockchain account you pick. Every transaction on that address gives one run, ready to hand to the next step.

How it fires
the app tells Zapier the moment it happens, so the Zap starts right away, whatever your plan.
When to use it
a treasury wallet on a test network should warn the finance lead whenever funds move in or out.
Watch out
the networks offered depend on the instance, since testnets sit on Sandbox and mainnets on Production, and only Ethereum-based chains are listed.
2

New Contract Event

Instant trigger

In Zapier“Triggers when a new event from a smart contract has been emitted.”

Point this one at a smart contract address and the Zap runs every time that contract emits a new event from its own code. The contract does the talking, Zapier listens.

How it fires
the app tells Zapier the moment it happens, so the Zap starts right away, whatever your plan.
When to use it
a token contract your team deployed on a testnet should feed a running log of its events, without anyone checking by hand.
Watch out
it asks for a Contract ID, the contract's own address, not a wallet address, so paste the right one before testing.
Actions

The 10 Overledger actions

Overledger gives you 10 actions. For each one: what it does for you, when to reach for it, and what to watch out for.

1

Create a Webhook

Action

In Zapier“Creates a new webhook to monitor either a user's blockchain account or a smart contract”

Sets up a new watch on Overledger, either on a blockchain account or on a smart contract, and sends what it sees to the address you enter in Callback URL.

When to use it
a new client wallet lands in your records and should be watched from its first transaction.
Watch out
the type you pick must match the address, Account for a wallet, Smart Contract for a contract.
2

Generate Overledger Request Body

Action

In Zapier“Generates the Overledger request body with sample data for both Read and Write requests to a smart contract”

Gives you a ready-made example of what a call to one contract function looks like, whether you plan to read from it or write to it. You only give the Function Name, and you get a template back.

When to use it
you are wiring a contract for the first time and want to see a well-formed request before filling a real one.
Watch out
the result holds sample data, so replace it with your own values before using it further down the Zap.
3

Get Swap Price From UniswapV2 Compatible DEX

Action

In Zapier“Returns the trade price between two tokens”

Asks a UniswapV2-compatible exchange for the swap price between two tokens: how much token B you would get for a given quantity of token A.

When to use it
a test trading flow should check the rate before it prepares any transaction.
Watch out
only the Sandbox instance is offered, and the default quantity of token A is 1 with 18 decimals, so set yours deliberately.
4

Prepare a Smart Contract Transaction

Action

In Zapier“Prepares a smart contract transaction for signing”

Gets a smart contract transaction ready for signing. You name the account it leaves from, the contract to call and the function to invoke, and Overledger returns what the signer needs.

When to use it
as the first half of a signing chain, just before Sign a Transaction.
Watch out
only Sandbox is available here, so whatever you prepare stays on test networks.
5

Read a Webhook

Action

In Zapier“Read information on a particular webhook”

Pulls the details of one existing watch, found by its Webhook Id, so a later step can show or check them.

When to use it
a teammate asks where a given watch sends its results, and the answer should come from Overledger itself rather than from memory.
Watch out
say whether that watch covers an Account or a Smart Contract, or the step looks in the wrong place.
6

Read Webhooks

Action

In Zapier“Read a list of webhooks”

Returns the list of watches on your Overledger instance, one type at a time: accounts, or smart contracts.

When to use it
an audit of everything being monitored, run from a Zap instead of by hand in Overledger.
Watch out
one run covers one type, so the full picture takes two of these actions, and two actions make the Zap multi-step.
7

Delete a Webhook

Action

In Zapier“Deletes a particular webhook”

Removes one watch by its id, so Overledger stops sending results for that account or contract.

When to use it
a client leaves, and the wallet tracked for them no longer needs watching.
Watch out
the type you set must match the watch you target, account or smart contract, exactly as when reading it.
8

Sign a Transaction

Action

In Zapier“Send a transaction to Overledger Authorise for signing”

Hands the transaction you just prepared to Overledger Authorise, which signs it. It closes the chain opened by Prepare a Smart Contract Transaction, and most of its fields come straight from that step.

When to use it
a test payment on a testnet should be signed without anyone copying values across.
Watch out
map Request Id and Native Data from the preparation step, set key Id to its Signing Account Id, and remember it is Sandbox only.
9

Read a Smart Contract Function

Action

In Zapier“Sends a read request for a particular smart contract function”

Calls a read function on a smart contract and passes its answer to the following steps, whatever value that function returns.

When to use it
right after a contract event, to fetch the current value the event touched.
Watch out
enter the return types in order, one per text box, and make them match what the function actually returns.
10

Update a Webhook

Action

In Zapier“Updates the callback url for a particular webhook”

Changes where an existing watch sends its results. You give its id and a new address in New Callback Url, and the watch stays on the same account or contract.

When to use it
the receiving system moved, and every watch should now point to its new home.
Watch out
only the destination changes; to follow another address, create a new watch instead.
When it breaks

When an Overledger Zap breaks

Zapier attaches no help article to Overledger and lists no limit of its own for it.

The traps below are Zapier's own, and they apply here as on any app. Know them before the first live run. When one hits anyway, start from Zapier troubleshooting.

  • No catch-up on past transactions

    A Zap only reacts to what happens after you switch it on. Transactions or contract events from before that are never picked up; moving the backlog is a separate job.

  • A Zap that keeps setting itself off

    If a step writes into the very place the trigger watches, the Zap starts itself again and again, and your task count drains fast.

  • Sudden bursts held back

    When a trigger suddenly returns a huge batch, after a bulk import or a migration, Zapier's flood protection can hold it back instead of running everything.

FAQ

Overledger and Zapier: common questions

01Is the Overledger Zapier integration free?
Yes, within the limits of the free plan. Overledger is not a premium app, so it works without paying. The free plan gives 100 tasks a month and builds Zaps of two steps: one trigger, one action. That covers a Zap such as New Account Event followed by Read a Smart Contract Function. Add a second action, a filter or another app after the first action, and the Zap becomes multi-step, which needs a paid plan. The preparation and signing chain takes two actions, so it sits on a paid plan.
02How many tasks does an Overledger Zap use?
One per successful action, and nothing for the trigger. When New Account Event or New Contract Event fires, no task is counted. Each action that completes counts once, so a Zap that prepares a transaction and then signs it uses two tasks per run. An action that fails is not counted at all. A few apps and a few actions take more than one task when they complete, so look at the count after the first runs before you scale a Zap up.
03Does the Overledger trigger work in real time?
Yes. Both Overledger triggers are instant: the app calls Zapier when the event happens, so the Zap starts right away on every plan, the free one included. The polling interval of each plan, 15 minutes on Free, does not apply to them. In the editor, a Zap built on an instant trigger shows a lightning bolt. The type is set by the app itself and cannot be switched from Zapier. If nothing starts, check the instance and the address set in the trigger first.
04What does connecting Overledger to Zapier require?
An Overledger account, plus access to any account or contract you do not own but want the Zap to touch. On Zapier, open the Apps page, click + Add connection, search for Overledger, click Add connection, sign in to Overledger in the tab that opens, then grant Zapier access. The connection is saved once and reused by every Overledger step. Each step then asks which instance to use: Sandbox for test networks, Production for main networks.
05Can Zapier sign Overledger transactions on a main network?
No, not with this integration as it stands. Sign a Transaction and Prepare a Smart Contract Transaction only offer the Sandbox instance, which reaches test networks. Get Swap Price From UniswapV2 Compatible DEX has the same restriction. Main networks need the Production instance, which the two triggers and the reading and watch actions accept. So a Zap can watch and read on a main network, but any signing flow built here remains a test flow.
06What if the Overledger operation you need is not on Zapier?
Then this integration cannot do it from the editor: it offers 2 triggers and 10 actions, and no search step. First check whether a combination gets close, for example Generate Overledger Request Body to shape a request, then Read a Smart Contract Function to run the reading. If the gap remains, the missing operation has to come from somewhere else, another automation tool or a request to the Overledger team. Note what the Zap must do exactly before comparing options.
07Zapier, Make or n8n for Overledger?
It depends on criteria, not on a winner. On Zapier, check that the 12 operations available cover your flow, that instant triggers matter to you, and that your volume fits a bill counted in tasks. Count the actions per run: each successful one is a task, and a second action means a paid plan. Make also lists an Overledger integration, so compare the operations on each side before choosing. For n8n, confirm what it offers for Overledger before planning on it.
