SDK Integration
The WASend SDKs provide a simple and consistent interface across all supported languages. Here's how to integrate them into your project:
TypeScript/JavaScript
# Using npm
npm install @wasend/core
# Using yarn
yarn add @wasend/core
Python
pip install wasend
.NET
dotnet add package Wasend.Core
Go
go get github.com/wasenddev/wasend-sdk-go
Integration Testing
The SDKs include integration tests that demonstrate proper usage. Here's an example of a typical session restart flow:
- Get session information
- Restart the session
- Verify the session status is STARTING
For detailed integration examples, refer to the SDK documentation and test files in each repository.
Response Fields
Field | Type | Description |
---|---|---|
uniqueSessionId | string | Unique identifier for the session |
sessionName | string | Name of the session |
phoneNumber | string | Phone number associated with the session |
status | string | Current status of the session |
createdAt | string | Timestamp when the session was created |
updatedAt | string | Timestamp when the session was last updated |
Error Codes
Code | Description |

Notes
- The session must be in a STOPPED state to be restarted
- After restarting, the session will be in a STARTING state
- Restarting a session will attempt to reconnect to WhatsApp
- The session may require QR code scanning after restart
- The SDKs handle error cases and provide appropriate error messages
- Integration tests demonstrate proper error handling
