Laravel Passport - Grant Type Not Supported
I have installed Laravel Passport per the documentation and I have modified all areas of my code that is required.
I am working on setting up Password Grant Tokens so that users will be able to get an API token when logging in with their username and password for the site. I am hitting an issue though when it comes to the grant_type. For some reason Laravel is complaining about an invalid grant type.
{
"error": "unsupported_grant_type",
"message": "The authorization grant type is not supported by the authorization server.",
"hint": "Check the `grant_type` parameter"
}
These are the fields that I am posting to /oauth/token
client_id = 4
client_secret = SMiYE7XqDNtXKQnmkYmFnXxfAaV83vRhnJ9zwCtZ
username = [email protected]
password = **************
grant_type = password
scope = *
I have run php artisan passport:install and I have also tried running php artisan passport:client --password
Both commands worked and both created the client and secrets, however, I cannot seem to get past the error about the grant_type.
Any suggestions on what I should look at to get this solved so that Password Grant Tokens will work for me?
Answer
It appears that you must send the parameters as form data and not in the headers like I was doing... Rookie Mistake!
