Prerequisites

At the marketplace level
The marketplace must be eligible for the specified voucher MID(s).
To make sure, make a GET request on the marketplace resource with the “vouchers” attribute:
```
GET /marketplaces/{uuid}
```
For example, for a marketplace eligible for CONECS and CVCONNECT MIDs, the response will contain the following object list:
```
...
  "vouchers":[
{
  	"contract_type":"CONECS"
},
{
  	"contract_type":"CVCONNECT"
}
  ]
...
```
These parameters are specified by the Lyra Collect services. You can contact tech support if you notice a deviation from the expected configuration.
At the sub-merchants’ level
The MID must be specified at the sub-merchant’s level.
For example, for a sub-merchant whose only active MID is CONECS:
```
GET /sellers/{uuid}
```
Example:
```
...
  "vouchers":[
{
  "contract_type":"CONECS"
  "contract_number":"1999011"
}
  ]
...
```
To create or activate a MID at the sub-merchant level via the onboarding API, see the corresponding documentation.
