Hi I have a problem after the first time I create the token
from the guide
after 40 minute the token expire and I need create another or refresh
but I receive a error
{“error”:“invalid_request”,“error_description”:“Incorrect request token”}
if I generate a new “code” (point 3) from
Sign up for Revolut Business&redirect_uri=https://example.com&response_type=code#authorise
work
is possiible?
Hi @Scoccia
When you obtained the first access_token (using the code parameter from the redirection), you also received a refresh_token in the response.
When the access_token expires, you can generate a new one using the refresh_token as described in Refresh the access token
If you didn’t save the refresh_token, then you will need to generate a new one.
thank you Samuel but I do this
curl https://b2b.revolut.com/api/1.0/auth/token \
-H "Content-Type: application/x-www-form-urlencoded"\
--data "grant_type=refresh_token"\
--data "refresh_token=(old_Token)"\
--data "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer"\
--data "client_assertion=(my_JWS)"
but the error is
{"error":"invalid_request","error_description":"Incorrect refresh token"}
Hi @Scoccia
I see you are sending old_Token which I assume is your expired access_token. This is not correct.
As an example, when you called /token the first time during setup, you should have received something like this in the response:
{
"access_token": "oa_prod_rPo9Om.......",
"token_type": "bearer",
"expires_in": 2399,
"refresh_token": "oa_prod_hQacSG........"
}
Note that there are two tokens, you should use the second one (refresh_token) to obtain a new access_token.
