I want to insert a row into a table that no user should have write access. What is the way to do this in this setup?

that is the default mode with hasura. Only admin can mutate/query data unless you specify extra permissions via roles

but how can I create a mutation after something has happened on the frontend?

since I dont want to execute it in the context of the logged in user

you could send the request to a serverless function instead and have it trigger the mutation for you. Why are you trying to do a mutation as an admin on behalf of user?

I want to create some subscriptions

but I dont want the user to create it

but it should happen after payment

ok, that makes sense. My suggestion would be to use a lambda function for that then. You can even connect a lambda function as a remote schema. So the user would call the lambda function and the lambda function would then implement the business logic you need and act as admin

is there documentation regarding this?

not for this particular use case but we have an example on how to do something similar, it might actually what you need in this case
