Postman Collection / Contract Negotiation

[ip312]

In the current Postman Collection Management-API/Contract Negotiations/Start Negotiation Request the fields "https://w3id.org/edc/v0.0.1/ns/offerId" and "https://w3id.org/edc/v0.0.1/ns/policy": {"@id": are hardcoded. Is it correct or shall both be replaced through own offer Id values? @tmberthold

Replaced by own values.

If I use the Management-API and want to start the ContractNegotiation, what is the offerId to be used?
The offer-id consists of the provider's contract-definition-id, the provider's asset-id and an additional UUID provided by the Provider. These are base64 encoded, appended to each other separated by a colon : and named as offer-id.
The response of the catalog-request contains the hasPolicy-id.
This hasPolicy-id should be able to be used as an offer-id according to the schema.
-> base64(contractDefinitionId):base64(assetId):base64(serverProvidedUuid)
