When implementing the Particle Health API, we typically advise our clients to launch their query process from the FHIR API route. Doing so gives optionality when choosing to implement FHIR data, C-CDA data, or both (depending on the use case).
As seen in the workflow diagram below, initiating a query from the Create Patient endpoint enables developers to choose which data format to download and gives the flexibility to pivot into a different data format down the road, if desired. Both FHIR and C-CDA have a separate set of endpoints to utilize, but the initiation of the query can happen with one step instead of two (starting with the FHIR
Patient create API call). The diagram below details how this flow would be implemented. This flow counts as a single query.
If you are leveraging our Flat data format, the recommended flow can be found here.
If you have any questions about the implementation of this flow or would like to consider another flow, please reach out to your Particle Health representative and we'd be more than happy to help!
