Cannot enable events URL in Slack API
This is my first post, and I'm a beginner at this so please be kind.
I'm running an integration on an AWS server, and the Slack API Enable Subscriptions page will not verify the Events Request URL. On the Slack API page, I receive the error "Your URL didn't respond with the value of the challenge parameter." but no other information.
Following the instructions here: https://www.tyntec.com/docs/whatsapp-business-api-integration-slack
Everything looks OK until the Enable Events step. where Slack throws the following error:
Here is the git repository https://github.com/tyntec/api-samples/tree/master/wa-integrations/slack
This is my postman code:
{ "webhooks": [{ "events": [ "MoMessage" ], "callbackUrl": "https://x.x.x.x/tyntec/forwardWAMessage" }] }
can you please nudge me in the right direction?
