# Postman Collection

### Using Postman to test SESTEK Text-to-Speech APIs

For easy testing using Postman, we provided a Postman Collection.

The files are available here:

1. [Download Postman](https://www.postman.com/downloads/)
2. [Text-to-Speech.postman_collection.json](https://cdn.document360.io/9bca2910-6a3b-4224-9470-43f91f9a6d57/Images/Documentation/Text-to-Speech.postman_collection.json)
        
      After downloading Postman and SESTEK Text-to-Speech Postman Collection, you can import the collection into Postman to get started.

#### Step 1: Get your API Client ID and Secret

Contact sales operation department and they will give you these credentials.

#### Step 2: Generate your Access Token

Using the POST Get Integration token API you will be able to generate anaccess token that will expire in 1 year from the time of token generation. You will be able to make a synthesis using this access token. Check [Authentication](/v1/docs/tts-authentication) for more info.

#### Step 3: Convert Text to Speech

After adding bearer token to your request header (authorization: type > bearer), you should write the text to your request body. Check [POST TTS](/v1/docs/post-tts) for more info.
