Create an API Key to Connect Your Own Systems or Zapier

Updated October 24, 2026

An API key lets your own systems post to Latter Years: a website contact form, your CRM, a scheduler or a Zapier webhook. An admin creates the key on the Import API page, copies it once, and pastes it into the other system. You can revoke a key at any time, and it stops working right away.

Find the Import API page

A community opens Settings, then Integrations, and taps Set up on the Import API card. An agency opens Leads, taps "Import families from a spreadsheet", then "Or post them from your website or systems with the Import API".

Only an admin creates and revokes keys. The Import API comes with a paid plan.

Create a key

Give the key a name that says where it lives, such as "Website contact form", so you know which one to revoke later. Then tick what the key may do. Tick only what your system uses: a key without a permission is refused on that endpoint, so a leaked key can do less.

A community's key that posts residents also asks for your attestation, once, that every roster sent with it carries prior express written consent from the families on it. You give the date and how you obtained that consent, and every import through the key inherits it. An agency's key posts the families who reached out to you, and nothing else.

Copy it now, because it is shown once

After you tap Create key, the full key appears in a box with a Copy button. This is the only time anyone sees it: Latter Years keeps only a fingerprint of the key, never the key itself. Paste it into the other system before you leave the page.

Lost a key?

Nobody can show it to you again, support included. Revoke it and create another, then paste the new one where the old one was.

Revoke or replace a key

Your keys list shows each key's name, the first characters of the key, when it was last used and what it may do. Tap Revoke beside one and the next request that uses it is refused.

To replace a key without a gap, create the new one first, switch your system over, then revoke the old one. There is a limit on how many active keys you can hold at once; when you reach it, the page says so, and revoking one frees space for a new one.

Where are the endpoints documented?

Below your keys, the page explains the endpoints a key can use, with example requests. Hand that card and the key to whoever sets up the other system.
