If you have a lot equivalencies stored in TES, looking up each institution's InstitutionID individually could be a time consuming task. You would have to have a series of individual calls to retrieve a full list of InstitutionIDs. This would ultimately slow down the loading process of a public or create a delay in creating a data file. To avoid this issue, you can use the GetEquivalencyInstitutionListByAccount API call to retrieve the InstitutionID for all institution for which you have an existing equivalency.
How it works:
Using the GetEquivalencyInstitutionListByAccount call provide the key ID (AccessKeyID) for your institution. You can optionally then set a specific page and number of records per page. If these values are left blank, then all results will be returned.
If you are planning a process to import equivalencies to a secondary system, it is recommended that you create an association between the TES InstitutionID and that Institutional listing in that system.
The method is now available through https://wsapi.collegesource.com/ web service.
