如何从 postman 触发具有多个参数的 Azure 数据工厂管道

Question

I have created a Azure Data Factory pipeline which have multiple pipeline parameter,which I need to enter all the time when pipeline trigger.Now I want to trigger this pipeline from postman in my local system and i need to pass parameters to pipeline from post.

Answer 1

Do you really need to use postman? I've posted examples of doing this with Powershell and with Python.

Powershell: How to pass arguments to ADF pipeline using powershell

Python: https://gist.github.com/Gorgoras/1fe534fd9b454412f81c8203c773c483

If your only option is to use the rest api, you can read about it and get some examples here: https://docs.microsoft.com/en-us/azure/data-factory/quickstart-create-data-factory-rest-api

Hope this helped!!

You can trigger Azure Data Factory via a policy in API Management.

I've added a sample here: https://github.com/Azure/api-management-policy-snippets/blob/master/examples/Trigger%20Azure%20Data%20Factory%20Pipeline%20With%20Parameters.policy.xml

Answer 3

Azure Docs doesn't provide examples on how to pass a parameter which I find weird also nowhere else on the internet have I found an example of how to pass multiple parameters via REST API, I guess most people use ADF shell to trigger it or python script.

Anyway, if someone else stumbles on the same question then here's the solution (which is quite simple).

Firstly, Create an Azure App Registration and generate client ID and client secret value.

Authenticate via REST API to get the Bearer Token

curl --location --request POST 'https://login.microsoftonline.com/${TENANT_ID}/oauth2/token' \
--form 'grant_type="client_credentials"' \
--form 'client_id="${CLIENT_ID}"' \
--form 'client_secret="${CLIENT_SECRET_VALUE}"' \
--form 'resource="https://management.azure.com/"'

The response will contain a Bearer token, use it to trigger the pipeline. Replace subscription id, resource group name, and adf name.

curl --location --request POST 'https://management.azure.com/subscriptions/${SUBSCRIPTION_ID}/resourceGroups/${RESOURCE_GROUP_NAME}/providers/Microsoft.DataFactory/factories/${ADF_NAME}/pipelines/trigger-pipeline-from-rest/createRun?api-version=2018-06-01' \
--header 'Authorization: Bearer ${BEARER_TOKEN}' \
--header 'Content-Type: application/json' \
--data-raw '{
    "date":"2022-08-22",
    "param1":"param1 value",
    "param2":"some-value"
}'

Note: The app should have contributor access to ADF to trigger the pipeline.
