Authentication with POST Webhook for Paypal

I am using Paypal’s API documentation here.

I’m trying to do a POST to the authentication endpoint to be granted an access token to use in future requests, however I keep getting a 401.

Here’s my setup in Zapier: 

Note: I did encode my CLIENT_ID:CLIENT_SECRET into Base64 (using https://www.base64encode.org/) prior to testing this call.

Not sure where I went wrong?

Hi @ential 

Did you use a pipe | to separate the un/pw as indicated by the field description?

 

Hi there @Troy Tessalone 

I did use a pipe | to separate username and password, then encoded it but no luck…

Any other suggestions?

Try w/o encoding the value.

I did try that without any luck.

I still get 401.

Have you tried this step yourself Troy to get an access token?

Perhaps try using the production API endpoint.

 

Zapier will handle the encoding for Basic Auth

 

Hey @Troy Tessalone Correct me if I’m wrong, but I am using the production endpoint in my initial screenshot in my first post?

I was able to generate a user token.

 

 “sandbox” is used for testing.

Check your PayPal Developer Portal.

 

What’s the production API endpoint then?

 

I couldn’t see that - but also wasn’t in Sandbox myself. Your screenshot above also has “sandbox” in it?
