Hi @Divakar Krishnan
Thanks for using Microsoft Q&A !!
When you are using a web activity you can pass headers using the headers property from Web Activity Settings tab as shown below -
Or you can pass headers as part of web activity dynamic content using the below properties in json
"headers":{
"X-API-Key":"xyz"
},
Please refer to Web activity in Azure Data Factory for details.
When you are using a REST API, you can configure authentication headers by using the json editor of the REST linked service and passing the required json properties -
Please refer to the Using authentication headers section of REST documentation.
Please let me know if you have any other questions.
Thanks
Saurabh
