Overview

What the Overflow Zapier integration does

The Overflow Zapier integration sends one event from Overflow to the rest of your tools: a contribution that has just been confirmed. It works in one direction. Overflow starts the Zap, and another app does the follow-up work. No code is involved, and Overflow is available on the free plan.

Three results organizations build first. A thank-you that never slips: Confirmed Contribution starts a Zap that emails the donor from your own mailbox. A giving log the finance volunteer can trust: the same trigger adds a row per gift to a shared spreadsheet. And a moment for the team: a short message in your staff chat each time a gift lands, which keeps everyone close to the campaign.

The trigger is instant. Overflow warns Zapier itself, so the free plan's waiting time between checks does not apply.

What Zapier does not do for Overflow: it cannot write anything into Overflow. There is no action to record a gift, refund one or edit a donor, and no search to find a past contribution. Overflow is always the start of the Zap, never the destination. Gifts confirmed before the Zap was switched on are not picked up, so your log starts on the day you publish.

Vocabulary

Zapier vocabulary in one minute

Seven words from the editor. One read and the rest of the page is straightforward.

Zap
The automation you build on Zapier: one trigger, then one or more actions that run each time that trigger event happens.
Trigger
The event in an app that starts the Zap. Once the Zap is on, Zapier waits for it; here, a contribution confirmed in Overflow.
Action
What the Zap does after it starts: the step that writes, sends or moves something for you, such as a thank-you email.
Task
The unit Zapier bills. One task is one action your Zap completes successfully, and your plan gives you a set number of them.
Instant vs polling trigger
An instant trigger is reported by the app as the event happens. A polling trigger is checked by Zapier on a fixed timer.
Filter
A step that lets the Zap continue only when what arrived meets a condition you set, and stops it every other time.
Multi-step Zap
Any Zap beyond one trigger and one action. A second action or a filter makes it one, and it then requires a paid plan.
Cost

What it really costs

Zapier bills tasks, not Zaps. The Overflow trigger costs nothing; each successful action in another app does.

  • Overflow trigger0 tasks
  • Each successful action1 task
  • Free plan100 tasks a month, 2 steps per Zap
  • Overflow on the free planYes, not a paid-only app

One task per successful action: a Zap that emails the donor and logs the gift in a sheet uses two tasks per contribution. A failed action is not counted. The free plan gives 100 tasks a month and unlimited Zaps, but each Zap stops at two steps, one trigger and one action. A filter or a second action means a paid plan. Plans also set how often Zapier checks polling triggers; Overflow has none, so the grid below is for reference only.

Connect

Connect Overflow to Zapier in three steps

  1. 01

    Open your connections

    In Zapier, open the Apps page of your account and click + Add connection. You need an Overflow account, plus access to anything in it you do not own but want the Zap to read.

  2. 02

    Find Overflow

    Search for Overflow by name in the dialog, select it, then click Add connection. The connection is your Overflow account linked to Zapier once, then reused by every Zap.

  3. 03

    Sign in and grant access

    Sign in to Overflow in the tab that opens and allow Zapier to access the account. The connection then shows in your Zapier list, ready for your first Zap.

First Zap

Your first Zap: thank every donor and log the gift

GoalEach contribution Overflow confirms triggers a thank-you email to the donor and a new row in your giving log.

  1. 01

    Build: pick the trigger

    Start a new Zap, choose Overflow as the app and Confirmed Contribution as the event, then select the Overflow connection you just set up.

  2. 02

    Test the trigger

    Run the test. Zapier brings back the three most recent contributions of the account, so you map the next steps on a real gift rather than a blank one.

  3. 03

    Add the thank-you

    Add your email app as the first action, address it to the donor from the contribution, and write a short, warm note in your own words.

  4. 04

    Add the log

    Add your spreadsheet app as a second action and map the gift details into its columns. Two actions make this a multi-step Zap, on a paid plan.

  5. 05

    Test, then publish

    Test each action once on your own address, check the sheet, then click Publish to switch the Zap on for every gift that follows.

Triggers

The Overflow trigger on Zapier

1 event starts a Zap when something happens in Overflow, and one of them is instant: the app calls Zapier straight away, whatever your plan.

1

Confirmed Contribution

Instant trigger

In Zapier“Triggers when a new contribution is confirmed in Overflow.”

Starts the Zap when Overflow confirms a new contribution. It is the only event the integration offers, and it covers the one moment that matters most to a fundraising team: a gift that has gone through.

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 church office or a small charity wants every donor thanked and every gift recorded in its own spreadsheet or donor database, without copying gifts over by hand.
Watch out
each confirmed gift runs every action in the Zap, so a big giving day spends tasks fast; size your plan for the peak.
When it breaks

When an Overflow Zap breaks

Zapier attaches no help article to Overflow and the source lists no limit specific to the app. These are the general traps, applied to fundraising.

Most surprises come from how the Zap is set up, not from Overflow. Four cases deserve a check before a campaign goes live. If a Zap still misbehaves, see Zapier troubleshooting.

  • Earlier gifts are not picked up

    A Zap only reacts to what happens after it is switched on. Contributions confirmed before that stay in Overflow; bringing them over is a separate job.

  • A giving day empties the plan

    Each confirmed gift spends one task per action. With two actions, every gift costs two, and the 100 tasks of the free plan can run out on a busy campaign day.

  • A large batch gets held back

    When a trigger suddenly sends a huge batch, after a migration for example, Zapier's flood protection can hold it back instead of running every item.

  • A filter that never passes

    Filter rules are typed. A text rule on an amount, or a number rule on text, and the condition is never met: the Zap stops at the filter each time.

FAQ

Overflow Zapier integration: frequently asked questions

01Is the Overflow Zapier integration free?
Yes, for two-step Zaps. Overflow is not reserved for paid plans on Zapier, so the free plan can use its trigger, with 100 tasks a month and unlimited Zaps. The limit is the shape of the Zap: one trigger and one action. If you want to thank the donor and also log the gift, or add a filter on certain gifts, the Zap becomes multi-step and needs a paid plan. You also need an Overflow account to connect at all.
02How many tasks does an Overflow Zap use?
One task per successful action, nothing for the trigger. A Zap where Confirmed Contribution sends a thank-you email uses one task per gift. Add a spreadsheet row and each gift costs two. An action that fails is not counted. Because every confirmed gift runs the Zap, your task use follows your giving volume closely, so look at your busiest campaign period, not an average month, when you choose a plan.
03Does the Overflow trigger fire instantly?
Yes. Confirmed Contribution is an instant trigger: Overflow tells Zapier the moment a contribution is confirmed, and the Zap starts straight away. The plan grid that sets how often Zapier checks polling triggers, 15 minutes on the free plan, does not apply to it. In the editor, a Zap built on an instant trigger shows a lightning bolt. For a donor, that means a thank-you that arrives while the gift is still on their mind.
04What does it take to connect Overflow to Zapier?
An Overflow account and a Zapier account. In Zapier, open the Apps page, click + Add connection, search for Overflow, sign in to Overflow in the tab that opens and grant access. If the Zap must read anything you do not own in the account, your user needs access to it. Before testing, make sure at least one contribution has been confirmed, since the test pulls the three most recent ones.
05Why did gifts from before the Zap never arrive?
Because a Zap only reacts to what happens after it is switched on. Contributions Overflow confirmed before you published the Zap are not sent, even if they appear in the test. The fix is timing: publish the Zap before a campaign or a giving day starts. Gifts already received have to be moved over once, as a separate job; the Zap then handles every new one. From the moment it is published, each confirmed gift reaches the Zap right away, since the trigger is instant.
06What if the Overflow operation you need is not on Zapier?
Then Zapier cannot do it for Overflow today. The integration has 1 trigger and nothing else: no action to record a gift, issue a refund or update a donor, and no search for past contributions. Anything that must be written into Overflow stays a task inside Overflow. What Zapier does well is carry each confirmed gift out to other apps, which offer far more actions. If writing into Overflow is central, compare other automation tools.
07Zapier, Make or n8n for Overflow?
Choose on criteria rather than reputation. On Zapier, Overflow offers 1 instant trigger and no actions, works on the free plan, and each run is billed per successful action in your other tools. The free plan limits Zaps to two steps. Check whether each tool offers the Overflow event you need, whether any can write back into Overflow, how each bills a run, and which volunteer or staff member will maintain the automation over time.
