This section helps guide you to create and manage your brands and campaigns using the API.

## Brands

Before you create a campaign you must create a brand and this must be approved. Brands can either be created and managed at the organisation level or workspace level. 

### Create and manage brands at organisation level

If you want to create and manage a brand that can be shared with one or more workspaces (for example your organisation is ACME), and you have a workspace for ACME marketing and ACME support that will use a 10DLC brand called ACME, you should use the organisation level endpoints for Brand creation and management

### Create and manage brands at workspace level

If you want a Brand to only belong to a single workspace (for example your organisation has many workspaces representing different customers) you should use the workspace level endpoints to create a Brand that belongs to a single workspace only

## Brand vetting

Once you have successfully created a Brand it is also possible to submit this for additional vetting

### Campaigns

Once you have an approved Brand, you can then create a campaign. Campaigns are always scoped to a workspace. This means if your Brand is shared with multiple workspaces each workspace must have it's own approved campaign before you can install any SMS channels with US 10DLC number's.
