Everything you need to integrate with the FundraiserMax API. Build custom workflows, sync donor data, and connect AI assistants to your fundraising platform.

Retry Policy

If your webhook endpoint does not respond with a 2xx status code within 10 seconds, FundraiserMax will retry the delivery using exponential backoff.

Automatic Disabling

If a webhook endpoint fails 5 consecutive deliveries (across any events), FundraiserMax will automatically disable the webhook and send an email notification to all account admins. You can re-enable the webhook from the Settings page after resolving the issue.

Best practice: Monitor your webhook endpoint health and set up alerting for failures. Return a 200 status code as quickly as possible — process the event asynchronously if it requires heavy computation.
