Invalid_auth_code trying to get the access token

Question:

[Explain the details of what you are trying to achieve. The more details you provide, the easier it is to understand what you need.]

What have you already tried:
I created a callback URL where I received the token when adding my app to my site, and received the token with success.

With the token, I tried to get the access token using:

curl -X POST \
  https://www.wixapis.com/oauth/access \
  -H 'Content-Type: application/json' \
  -d '{
    "grant_type": "authorization_code",
    "client_id": "fa....",
    "client_secret": "3f.....",
    "code": "...the token received on callback route..."
}'

....

{"errorCode":20002,
"errorDescription":"[business][RECOVERABLE][OAuth2 provider] c.w.o.p.s.c.HandleExceptions$BadRequestWithSpecificMessageResponse - invalid_auth_code",
"success":false,
"payload":{"message":"invalid_auth_code"}}%

Where:

  • “client_id”: is my app id
  • “client_secret”: is my app secret
    Both got on my app “oauth” menu

Could you helpme please?

You maybe need a CODER for your project, if you have several tasks…
