I can do the entire authentication process according to the official guide at the following link:
https://shopify.dev/docs/api/customer#step-use-access-token
I get the token correctly and when analyzing the id_token
you can see the correct information, but the acces_token indicates that it has an incorrect signature and shopify returns me
{
“errors”: [
{
“message”: “Not a valid access token”
}
]
}
I attach the screenshots of postman
