External Collection > Using Dynamic values

Get Help External Collections, Custom Actions & Collections

I need help with an External Collection (GET method).

When I use manually written values in the headers, it works just fine and I am able to save the External Collection and continue my work.

BUT, there are 2 headers that should bring Dynamic values from my User’s collection.
One of them is the bearer token, and the other one is the user_id.

And when I try to set the collection with Dynamic values from my User’s collection the API shows me as failure and doesn’t allow me to save the External Collection.

What should I do?

Hello,
When dynamically fetching a bearer token and user_id from a user’s collection for External Collection headers, common issues preventing saving include incorrect data type/format, asynchronous loading of values (leading to nulls during setup), or platform restrictions on dynamic header configuration at save time. Ensure the values are correctly formatted and available, or use pre-request scripts/intermediary functions if your platform requires runtime injection rather than static saving of dynamic headers.
