Salesforce Professional edition has no available API access by default. But, you can temporarily turn it on by contacting your Salesforce Account Executive and request that API be provisioned as courtesy.
Step-by-step instruction from Salesforce support
You can enable your Salesforce Professional API for a maximum of two weeks.
To that, email Salesforce Customer Support with an answer to the following questions:
- Are you the System Administrator authorized on behalf of this Organization to make this request? Do you understand the implications of getting the API access?
- What is the Organization ID (where you would like to get the API access)?
- How long would you like for the API access to be applied? (Maximum of two weeks)
NOTE: It can only be requested singularly. Requests spanning concurrent two week periods will not be granted.
- Why do you need to get an API limit access? (What is the business case?)
- Are you doing a data upload or data migration? Is this increase for an integration?
Information to include in your request for a data upload or data migration
How many records and what objects will you upload? (What Salesforce means under “objects” check out here).
What batch size is being used? (What Salesforce means under batch size check out here; Trujay default batch size is 200).
What tool will be used? (The bulk API allows to upload 10,000 records/batch x number of batches).
Information to include in your request for an integration
What specific API calls will the integration be sending and how many?
What application will be used?
In case you have some issues with getting the Salesforce API access or its implementation, feel free to contact Trujay expert, to get useful insights.
After enabling API access in Salesforce, you should inform your Trujay account manager about the exact time you have your API available to set up your CRM data migration.
