I am attempting to create a REST integration with Square (https://developer.squareup.com), but am receiving a 302 Found error when I attempt to send a webhook via Square.

My API is working successfully when tested through Workbench with the payload that is being sent via Square, at the URI of /services/apexrest/[SOBJECTNAME]/[RESTRESOURCENAME].

My endpoint URL is as follows: https://ORGNAME--partial.lightning.force.com/services/apexrest/[SOBJECTNAME]/[RESTRESOURCENAME] which generates a 302 Found error, meaning that the endpoint is redirecting. I am unable to process the redirect via Square.

I have tried playing around with different base URLs for the endpoint per the Salesforce documentation and other forum posts, for example ORGNAME--partial.my.salesforce.com (401 unauthorized), ORGNAME--partial.INSTANCE.my.salesforce.com (307 redirect), and ORGNAME--partial.INSTANCE.force.com (401 unauthorized) to no avail. I am unable to use ORGNAME--partial.salesforce.com for the subscription endpoint per Square.

Hoping someone has run into this issue before. Thank you!

Following up on identigral's comment, I have created a Site with the value of https://ORGNAME-square.INSTANCE.force.com/square/ and have updated my webhook endpoint accordingly to https://ORGNAME-square.INSTANCE.force.com/square/services/apexrest/[SOBJECTNAME]/[RESTRESOURCENAME]. Now getting a code of status 500 Internal Server Error.

I should add that I also have a Remote Site Setting with the appropriate value of https://connect.squareupsandbox.com.

    It works in Workbench because you're authenticated. For a typical webhook, your REST endpoint must be public - see answer by gils in this Q&A for a howto

  • Hello @identigral! I have a site set up now and am getting a 500 error.

  • It's unclear on what API you're calling after you've created the Site and what your webhook is doing. Please edit your question and provide a Minimal, Reproducible Example. See How to Ask and Help Center for guidance on this.

  • What is the urlMapping you've specified in your @restResource annotation?

  • Hi @DerekF, the urlMapping is /[SOBJECT]/[RESTRESOURCENAME], as specified in the URI. I have verified spelling and capitalization.

Just posting the follow up as to what the issue was. We were able to solve this via @identigral's comment of setting up a site and debugging through the Site Guest User. The resulting 500 error was caused by Square sending the same payload multiple times and duplicate detection bouncing it back.
