Update: Geneious Cloud will soon offer a REST API for direct upload of data to Geneious. If you are interested, please contact us to discuss.
Geneious Prime's Local and Shared Database solutions do not currently provide an API to access data directly (such as REST). However, several less direct options are available for integration. These are covered in What is the best way to integrate with a LIMS?
While the Geneious Prime shared database is backed by a relational database, we do not provide technical support for direct access via SQL. The schema is undocumented and subject to change at any time, without warning, so we strongly discourage this.
Similarly, the .geneious file format is not designed for other programs to parse as it is undocumented and subject to change.
