Watch a brand, usually a competitor, by its website, the same as Watch a brand on the dashboard’s Competitors page. If the brand is already in the Sequenzy email gallery, you watch it at once: the watch comes back available, and its emails are in List Watched Brand Emails. Otherwise the brand is requested, the same as Request a Brand, and its emails show up once it is added and they are collected. New emails usually arrive a few hours after they are sent. Watching again keeps the one watch: it returns 200 with created set to false, and a new note replaces the old one, so a retry never duplicates. Your company can keep up to 50 watches and brand requests together. Requires the templates:write scope.

Request

string

required

The brand’s website or domain, up to 255 characters, such as competitor.com or https://competitor.com/pricing. It is reduced to the registrable domain, so www.competitor.com and competitor.com are the same brand. Your own website returns 400.

string

Optional, up to 300 characters: what you want to see from the brand, such as its onboarding emails.

curl -X POST "https://api.sequenzy.com/api/v1/gallery/watchlist" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "website": "linear.app" }'

Response

boolean

true for a new watch (status 201), false when you already watched this domain (status 200).

object

The watch, with the same fields as in List Watched Brands.

string

What happens next.

A 400 also means the website is not a valid domain, or that your company already keeps 50 watches and brand requests; stop watching some with Stop Watching a Brand first. A 422 means the body failed validation, such as a missing website or a note over 300 characters.
