Getting a 413 error - how do I fix 'Request Entity Too Large'? or Why am I seeing a 413 error and how

413 error’s usually a server limit thing.

If you’re on Nginx, add this to your config:
`client_max_body_size 256M;`

For Apache, it’s `LimitRequestBody`.

If you’re using a CMS like WordPress, plugins like “Increase Maximum Upload File Size” can help.

For APIs, consider pagination or streaming data instead of one big request.

Also, Postman’s great for testing larger payloads before hitting the server.
