In order to link a Cost Line to a Meta campaign, the Supplier of the Cost Line must be linked to Meta. For more information, see Supplier Linking and Mapping.  | 
Each Cost Line on the Social grid can be linked to one or more Meta campaigns, reducing the need to manually re-enter details across multiple platforms. Linking a Meta campaign also creates a connection that allows delivery costs and metrics to flow from Meta to OneStrata.
The linked Meta campaign can be a new campaign or an existing campaign:
| Linking Option | Description | 
|---|---|
| Link to a new Meta campaign | In OneStrata, upload a Cost Line to Meta to create a new Meta campaign. The Cost Line is automatically linked to the newly created campaign.  | 
| Link to an existing Meta campaign | In OneStrata, link a Cost Line to an existing Meta campaign.  | 
To create a new Meta campaign and link a Cost Line to the newly created campaign, do the following:
| Field Name | Step(s) | 
|---|---|
| Select Campaign / Create Campaign | Check that the Create Campaign option is selected. If not, select Create Campaign. |
