Postman request Body
While constructing requests, you will be working with the request
body editor a lot. Postman lets you send almost any kind of HTTP
request. The body editor is divided into 4 areas and has different
controls depending on the body type.
Note about Headers: When you are sending requests through the HTTP protocol, your server might expect a Content-Type header. The Content-Type header allows the server to parse the body properly. For form-data and urlencoded body types, Postman automatically attaches the correct Content-Type header so you don’t have to set it. The raw mode header is set when you select the formatting type. If you manually use a Content-Type header, that value takes precedence over what Postman sets. Postman does not set any header type for the binary body type.
Uploading multiple files each with their own Content-Type is not supported yet.
This encoding is the same as the one used in URL parameters. You just need to enter key-value pairs and Postman will encode the keys and values properly. Note that you cannot upload files through this encoding mode. There might be some confusion between form-data and urlencoded so make sure to check with your API first.
A raw request can contain anything. Postman doesn’t touch the string entered in the raw editor except replacing environment variables. Whatever you put in the text area gets sent with the request. The raw editor lets you set the formatting type along with the correct header that you should send with the raw body. You can set the Content-Type header manually too and this will override the Postman defined setting. Selecting XML/JSON in the editor type enables syntax highlighting for your request body and also sets the Content-Type header.
Tip: Selecting text in the editor and pressing CMD/CTRL + B can beautify the XML/JSON content automatically.
Binary data allows you to send things which you can not enter in Postman, for example, image, audio, or video files. You can send text files as well. As mentioned earlier in the form-data section, you would have to reattach a file if you are loading a request through the history or the collection.

Form-data
multipart/form-data is the
default encoding a web form uses to transfer data. This simulates
filling a form on a website, and submitting it. The form-data editor
lets you set key-value pairs (using the data editor)
for your data. You can attach files to a key as well. Note: due to
restrictions of the HTML 5 spec, files are not stored in history or
collections. You will need to select the file again the next time you
send the request.Uploading multiple files each with their own Content-Type is not supported yet.
Urlencoded
This encoding is the same as the one used in URL parameters. You just need to enter key-value pairs and Postman will encode the keys and values properly. Note that you cannot upload files through this encoding mode. There might be some confusion between form-data and urlencoded so make sure to check with your API first.
Raw
A raw request can contain anything. Postman doesn’t touch the string entered in the raw editor except replacing environment variables. Whatever you put in the text area gets sent with the request. The raw editor lets you set the formatting type along with the correct header that you should send with the raw body. You can set the Content-Type header manually too and this will override the Postman defined setting. Selecting XML/JSON in the editor type enables syntax highlighting for your request body and also sets the Content-Type header.
