invalid_params
HTTP 422, application/problem+json. When: params or metadata do not match the schema, or callback_url is not allowed.
What to do
params or metadata do not match the schema, or callback_url breaks the URL rules (pointer /callback_url). errors[] lists each problem as {pointer, message}, where pointer is a JSON Pointer from the root of the request body (for example /params/website_key). The parameters of each type are on its task type page.
See all codes on Errors. Include the request_id when you contact support.
