I am developing a bubble plugin for a payment gateway, but before running an API call there is a pre-request script that is executed , this script provides the Authorization header value.

But I am not understanding where should I put the script in the plugin editor and get value of the API Authorization header in the API section of the plugin editor.

Hi @himanshu.s

The answer from the Bubble team is below. I hope it helps

"Hi Eren,

Thanks for reaching out. Plugins have an object called ‘context’ with some Bubble utilities. For example context.async – call context.async with a function that kicks off an asynchronous operation, taking a callback taking (err, res). Returns res or else throws error. Would that way of doing a callback work for your use case?"
