Bulk Generate Links

Bulk generate creates every combination of source, medium and content for one campaign and one destination in a single pass. Each link is checked against its template, duplicates are skipped, and new links are saved as drafts.

Before you start

You need edit access to Relay in the company. Read-only users are sent back with "You have read-only access to Relay in this company."
Sources and mediums are picked from approved-value lists. A Terrain definition with approved values for utm_source and one for utm_medium must exist, or the pickers show "No vocabulary bound." See Taxonomy.
The campaign must exist and not be archived. Its agreed value becomes utm_campaign on every link.

Generate links

Go to Relay > Links and click Bulk generate (also on the Relay dashboard under Create).
Under Set up, pick the Campaign and the Template, and enter the Destination URL, for example https://www.example.com/spring-sale.
Optional: enter a Title prefix. Each link is named "prefix - source - medium - content".
Under Combinations, tick the Sources and Mediums you want. In Content, enter utm_content values one per line, for example carousel_a and story_a. Content is free text; leave it empty for no content value.
Check the count, for example "12 links from 2 sources x 3 mediums x 2 content values."
Review the Preview: each row shows the title, source, medium, content and final URL.
Click Create N links.

Every selected value is crossed with every other. One run creates at most 200 links; narrow the combinations if you need more.

Check it worked

The Result column shows Created or Refused on each row, with the reason for a refusal. A message confirms how many were created. New links are drafts: review them in the link library, then set them active.

Click Export preview as CSV to download the preview (relay-bulk-preview.csv) before or after creating.

Duplicates and refusals

A row with the same destination, source, medium, campaign and content as an existing link is marked "Already exists - will be skipped" and is not sent.
Each new link is validated against the template on the server, the same as a single link. A required field the template expects but the builder does not fill, a value off a closed list, or a value over a length cap refuses that row only. The rest are still created.

Troubleshooting

Symptom	Cause and fix
"No vocabulary bound." in Sources or Mediums	No approved-value list exists for that parameter. Create one in Terrain
Create stays disabled	Pick a campaign, enter a destination, and tick at least one source and one medium
"A single run creates at most 200 links"	Reduce the sources, mediums or content values
Rows refused with a template message	The template requires something the builder does not set, or a value breaks a rule. Pick another template or adjust it on Templates
