Note that creating new source types requires that a developer write code.
Create a new Import Sources record for your data. This record ties a import source type to the entity to which you are importing the data. Also, you can specify an object that overwrites the default record matching and posting behavior with your own business logic. See Creating Import Sources.
This assumes that a suitable Import Source does not already exist. However, you can use an existing source if your system already has a record that specifies the data's source type, its fields, and the target entity.
Note that creating your business logic for the matching and posting processes requires that a developer write code. Alternatively, you can define and modify matching criteria while running the Generic Import wizard, reducing the amount of code a developer needs to write to specify different matching logic. See Running the Generic Import Wizard for more details.
Match import run details with existing records in the entity within the Import Runs record that was automatically generated by the wizard. Then, post the import run details to create new records for unmatched items. See Matching and Posting Import Results.
Review the newly created records to confirm that the data was successfully imported into Aptify.
