Making Etsy OAuth2.0 call via Postman

Question

I am new to Etsy API development and I have been stuck on it for days. I have tried going through the doucmentation to find some resource so that I can make a simple API call (I plan to convert it to code but I want to get it running via Postman to see if it even works).

Please let me know if this is not the right platform and where should I post this? THANK YOU in advance.

Link to docs: https://developers.etsy.com/documentation/reference

I have tried adding headers but it still does not work. What am I doing wrong?

Answer 1

https://developers.etsy.com/documentation/essentials/oauth2

steps:

1. First create the app : https://www.etsy.com/developers/register

2. Now add call back URL by editing the app: https://www.etsy.com/developers/your-apps , go here and click the app name then scroll down and edit call back url :

and add below url: https://oauth.pstmn.io/v1/callback

If you cannot access the page to edit, look at the URL. If it reads "etsy.com/au/%20/developers/edit..." then delete "/%20" and retry.

3. now add below informations:

Token Name : any name
Grant Type: Authorization COde PKE
Callback URL : https://oauth.pstmn.io/v1/callback ( keep authroize using browser unchecked)
auth url: https://www.etsy.com/oauth/connect
Access Token URL: https://api.etsy.com/v3/public/oauth/token
Client ID: Your appi KEYSTRING
Client Secret: YOUR app secret
Code Challenge Method: SHA256
Code Verifier: leave blank
Scope: scope eg: transactions_r (if using multiple scopes, separate each with a space, not with "%20" as the documentation says)
State: superstate
Client Authentication: Send Client Credentials in body

secret and keystring :
