Stripe Subscription API

[abalgir]

Hello,
I am trying to create a scheduled subscription at a specific date with Stripe. This feature exists neither in the Stripe plugin or Stripe.js plugin.
Hence I am configuring the API connector and having issues understanding why I am having this error message when initializing.
The values in the key are taken from Stripe logs.
Any help is appreciated.

Best
Gerard

Add the content type it says to in the header. Check all parameters as Queryst.
