I create new extension from partner dashboard, but I can’t call thi trigger from postman. Error: Invalid trigger_id
Can you post the exact request you made?
Make sure you’ve created the trigger according to the instructions on this help page. There are also instructions for testing your trigger within Flow there.
Sometimes this error can happen if you don’t have the proper auth header.
Do you have any documents here? I passed X-Shopify-Access-Token and Content-Type in header already
See docs on auth here
Is it possible you’re using an access token for a different shop or app?
