The error message you are seeing:

Unable to decode body because HTTP Request Method was "GET" but only [POST PUT PATCH] are supported.

indicates that you are making a GET request to an endpoint that expects a request body, which is only supported for POST, PUT, or PATCH methods. In Ory Kratos, the login flow works as follows: - To initialize a login flow, you use a GET request (e.g.,

/self-service/login/api

or

/self-service/login/browser

). - To submit the login credentials (such as username and password), you must use a POST request to the

action

URL provided in the login flow response. This POST request should include the required payload (e.g., identifier, password, method, etc.) in the body, typically as JSON for API flows or as form data for browser flows. If you attempt to send a body with a GET request, or try to perform the login submission step with GET instead of POST, you will encounter this error. Make sure you are: 1. Initializing the login flow with a GET request. 2. Submitting the login form with a POST request to the

action

URL provided in the flow response, including the necessary data in the request body. For example, after initializing the login flow and receiving the

action

URL, you should do something like:

bash curl -X POST -H "Content-Type: application/json" \   -d '{"identifier":"<mailto:user@example.com|user@example.com>","password":"yourpassword","method":"password"}' \   "<https://your-kratos-url/self-service/login?flow=flow-id>"

This approach is documented in the Ory Kratos login flow documentation and API reference. If you use GET instead of POST for the submission, you will get the error you described [Login Flow Payloads](https://www.ory.sh/docs/kratos/self-service/flows/user-login#login-flow-payloads) [API Reference](https://www.ory.sh/docs/kratos/reference/api#updateLoginFlow). If you need more details on the correct flow, please refer to the official documentation linked above.
