These tutorials use the Cognitive Services Text Analytics API. Microsoft already provides a connector for this API. It's a good example for teaching the custom connector lifecycle and how custom connectors can support unique scenarios.
Scenario
The connector you build exposes the Text Analytics Sentiment operation, which returns the sentiment score (0.000 to 1.000) for the text input.
Prerequisites
One of the following subscriptions:
- An Azure subscription (Logic Apps)
- Power Automate
- Power Apps
Basic understanding of how to create Logic Apps, Power Automate flows, or Power Apps.
API key for the Cognitive Services Text Analytics API.
Get an API key
The Text Analytics API uses an API key to authenticate users. When a user creates a connection to the API through a custom connector, the user specifies the value of this key. To get an API key:
Request an API key to try out the API. This doesn't require an Azure subscription.
Add the Text Analytics API to your Azure subscription. Once you have the API resource in your subscription, get the API key from the Keys section:
