2018-10 Breaking changes
REST API v. 1.0, mainly used by the previous version of the Salesforce connector, was discontinued on Sep 30th
Unused developer accounts were discontinued on Sep 30th
The SOAP API is now marked as "no longer recommended to use if you are starting a new project or planning to extend an existing one". REST API covers the feature set of the SOAP API.
- Access tokens must now be refreshed every hour either for SOAP or REST (it was 15' for the REST API). As the SOAP API is now using the same Authorization methods as the REST API, the expiration of the validity time is now the only way to dismiss a token and to deny the access. Any call to “logout” SOAP methods has become useless.
