IdentityHub – Array of VCs vs Single VC per Entry (Gaia-X Generated Credentials)

[zyedZ]

Hi all,
I am currently integrating Gaia-X generated Verifiable Credentials (using gx-credential-helper) into EDC IdentityHub.
The Gaia-X generator produces a bundle (array) of VCs representing a Self-Description (e.g. LegalPerson, Issuer, Address, etc.).
When attempting to store the credentials in IdentityHub, I tried submitting the array as generated, but it was not accepted.
I would like to clarify:

• If arrays are not supported, is there a recommended best practice for handling Gaia-X Self-Description bundles within IdentityHub?

Thanks in advance for your guidance.

Generally you have two ways to "insert" verifiable credentials into IdentityHub:

1. via DCP Credential Issuance Flow. This is the recommended way how you get credentials issued from an official issuer. The issuer must support the DCP Issuance Flow as well.
2. using IdentityHub's Identity API (which is basically its management API). This approach requires that the Issuer sends the credentials to the holder out-of-band, who then inserts them into IH via said API.

From your line of questioning I gather you are not familiar with either of those and I strongly recommend reading up on them.
