    • Workflow Steps

  • Step 1: Webhook Trigger
    The workflow is triggered via a webhook when a POST request is sent to the specified endpoint, replace-image-in-slide.

    - Step 2: Parameter Check
    The workflow checks if all required parameters (presentation_id, image_key, and image_url) are provided. If any are missing, it returns a 500 error response.

    - Step 3: Retrieve Slide Elements
    If all parameters are present, the workflow retrieves all elements from the specified Google Slides presentation using the Google Slides API.

    - Step 4: Find Image Object IDs
    The workflow searches through the retrieved slide elements to find the object IDs of images that match the provided image_key.

    - Step 5: Replace Images
    Using the found object IDs, the workflow sends a batch update request to the Google Slides API to replace the images and update their alt text.

    - Step 6: Respond to Webhook
    Finally, the workflow responds to the webhook with a success message once the image replacement is completed.

    - Add Additional Fields: Users can expand the JSON body in the Replace Images node to include more requests if needed, such as updating text elements or other slide properties.
    - Integrate with Other APIs: This workflow can be linked with other APIs to pull dynamic data for images or presentation content, allowing for more complex automation scenarios.
