In SyncSpider, one module can be used:
as a source integration which receives data from that source system
as a target integration which prepare or push data to the target destination
or as both source and target.
A user has a choice to set it up to suit their needs.
Custom API allows you to customizes the SyncSpider API and uses it as a storage for data.
In the module, the data is modeled to meet certain expected structure and SyncSpider then exposes a REST service that allows external systems to push and pull data to/from SyncSpider (as storage).
In this case, you can think of SyncSpider just as a storage for data.
Of course, it is much more than that, because a user can then say what should be done using some other integration once the data comes to the storage (e.g. sync data to another system).
External API allows you to connect every supported SyncSpider module with external API's systems.
⦁ Define external system API point
⦁ Define the request method
⦁ Define the auth type
⦁ Define the payload to API point
⦁ Define the fields type in schema (Optional)
With the External API a user makes SyncSpider push data to the generic external API.
When connecting a systems that don't have an existing standard integration modules often the best approach is to do the following:
1.Create a Custom API module that will handle the data pushed from your external API systems
2.Add an External API module that will push the data back to your external API systems.
