# Submit transaction

`POST /transactions`

**Submit transaction using JSON without additional tools**

  * Send [POST /transactions/signing_message](#operation/create-signing-message) to create transaction signing message.
  * Sign the transaction signing message and create transaction signature.
  * Submit the user transaction request with the transaction siganture. The request header "Content-Type" must set to "application/json".

For example: * `0x1` * `0x1668f6be25668c1a17cd8caf6b8d2f25` Move `vector` type value is serialized into `array`, except `vector<u8>` which is serialized into hex-encoded string with `0x` prefix. For example: * `vector<u64>{255, 255}` => `["255", "255"]` * `vector<u8>{255, 255}` => `0xffff` Move `struct` type value is serialized into `object` that looks like this (except some Move stdlib types, see the following section): ```json { field1_name: field1_value, field2_name: field2_value, ...... } ``` For example: `{ "created": "0xa550c18", "role_id": "0" }` **Special serialization for Move stdlib types:** * [0x1::string::String](https://github.com/aptos-labs/aptos-core/blob/main/language/move-stdlib/docs/ascii.md) is serialized into `string`. For example, struct value `0x1::string::String{bytes: b"hello world"}` is serialized as `"hello world"` in JSON.
