Explain how to create and configure an integration using a connector system, including endpoints, base URL, query parameters, headers, and testing with HTTP request and response, while noting logging cautions.

Test your first integration by calling the /users endpoint with postman, verify the HTTP request and response details, then convert the JSON body into Appian values for easy data rendering.

Learn to call an Appian integration from an expression rule and an interface, test via the console, and access complete data in a local variable for use in process models.

Call an integration in the process model with the call integration smart service to invoke get integration, map inputs and outputs, and handle success or error to drive the workflow.

Create a post integration in Appian by triggering a post request to the users api, sending a json body with name and job, and testing with dynamic rule inputs.

Learn how to invoke a post integration from Appian rules and interfaces, test it, and configure on success and on error, using save into to store the result.

Test post integration in the process model by triggering the git integration and creating a user with name Udemy, platform, and job fields, and verify the post results.

Learn how to authenticate API requests by using an API key, obtain and configure the key in RapidAPI headers, test with Postman, and apply it in Appian connectors.

Connect to a superhero API using an HTTP connector, configure an API key in the header, and test requests to retrieve a list of heroes for reusable integrations.

Learn to build an Appian integration to fetch and format user data, then display it in a card-layout interface with images and pagination.

Create your first web API in Appian using a hello world template, set the get endpoint, and test the API via its URL and Postman.

Configure the API body by converting data to JSON with the to_json function, create key-value pairs, add date and success fields, and review status codes, headers, and authentication.

Master basic authentication in Postman by using environment variables for username and secret password, and reference them with curly braces to test the Appian API securely.

Learn to test a secured API endpoint using curl by embedding basic authentication in the header, using encrypted snippets from Postman, and understanding authorization.

generate and use an api key in appian with admin access and a service account. pass the key in the appian api key http header to authenticate web APIs.

Diagnose 404 issues by checking client-side triggers and security permissions, ensure the service account has viewer access, add it to the users group, and verify API key authentication in postman.

Create a query record API using a get method to fetch all customer records, configure the endpoint, and test with console and Postman to verify data access.

Learn how to pass query parameters to a web API and fetch them with an HTTP request, including retrieving query parameters, the body, and headers, and test with Postman.

Add validation to a web API by checking for null or empty data and returning a failed response with a data not present message, using conditional logic.

Configure a document download endpoint in a web API template, including document ID handling, extension whitelisting, and content-disposition headers to trigger downloadable outputs tested via Postman.

Learn how to create and test a post API that writes new records to the Voff customer table using a JSON body, with endpoints, write records, and error handling.
