Salesforce Integration with Vision API | The Ultimate Guide

Integrating Salesforce with Google Vision API requires the following credentials: 

1. Salesforce Credentials: You will need to have a Salesforce account with admin permissions to set up the integration. 
2. Google Cloud Credentials: You will need to have a Google Cloud Platform account and enable the Google Vision API service. This will give you access to the necessary credentials, including a Project ID, API Key, and Service Account credentials. 
3. OAuth 2.0 Credentials: You will need to create an OAuth 2.0 client ID in your Google Cloud Console and configure it to allow access to the Google Vision API. You will also need to create an OAuth 2.0 Connected App in Salesforce to allow the integration to access Salesforce data. 
4. Integration Credentials: You will need to set up the integration between Salesforce and Google Vision API using the credentials obtained above. This can be done using middleware or custom code. 

It is important to follow the security best practices for handling and storing credentials, such as encrypting sensitive information and limiting access to authorized personnel.

Integrating Salesforce with Vision API using REST: 

• Create a Salesforce Connected App: To start with, you need to create a connected app in Salesforce. This will generate the required credentials, which you will use to authenticate the API requests. You can create the connected app by navigating to Setup > App Manager > New Connected App. 
• Set Up Vision API: You need to set up and configure the Vision API on the Google Cloud Console. This will generate the necessary credentials for authentication and API access. 
• Set Up OAuth 2.0: You need to set up OAuth 2.0 authentication in your Salesforce org to allow the Vision API to access your Salesforce data. You can do this by navigating to Setup > Security > Auth. Providers. 
• Build the API Integration: To integrate the Vision API with Salesforce, you need to build a REST API integration. This involves creating custom Apex classes and REST endpoints to send data to and receive data from the Vision API. You can use the Salesforce REST API to perform the integration. 
• Test and Deploy: Once you have built the integration, you need to test it thoroughly to ensure it is functioning as expected. Once you have confirmed that everything is working correctly, you can deploy the integration to your production org. 

Here is an example of how to use REST API to send an image to the Vision API for processing:

In the above code, we create an HTTP request object and set the necessary headers, including the OAuth access token for authentication. We then encode the image data in base64 format and add it to the request body. We also specify that we want to perform text detection on the image. Finally, we send the request to the Vision API and receive the response.
