Connect Enom to Lemon Domains
Three steps: create a read-only API key at Enom, add it to Lemon Domains, and your domains sync once a day from then on. Connect as many Enom accounts as you have.
Create a read-only API key at Enom
Enom API tokens act for the whole account, from allowlisted IP addresses only. Lemon Domains only ever calls GetAllDomains, which reads your domain list. Use a token rather than your password so you can revoke it on its own.
- 1Sign in to Enom and open Resellers → Manage → API.
- 2Add the Lemon Domains IP address shown on this page to the API IP allowlist and click Add.
- 3In the API Token Manager, generate a token named “Lemon Domains” and copy it.
- 4Enter your Enom login ID and the token in Lemon Domains.
Add it to Lemon Domains
- 1Sign in to Lemon Domains (it's free), open Connections and choose Enom.
- 2Give the connection a friendly name, like “Enom personal” or “Enom clients”. Connect each Enom account separately.
- 3Paste your login id and api token.
- 4Click Test connection. Lemon Domains checks the API key and shows how many domains it can see, without saving anything.
- 5Tick the checkbox to confirm you understand the risks, pick the project new domains go into, and click Connect and import. Your domains appear straight away and sync once a day after that.
What Lemon Domains reads
- Domain names (including internationalised names)
- Status, such as active, expired or pending transfer
- Expiry and registration dates
- Whether auto-renew is on
- Transfer lock
Lemon Domains only ever sends read requests to Enom: each integration has a fixed list of read-only calls it may make, so it never renews, transfers or changes a domain. Your API key is encrypted at rest and never shown again.
If something goes wrong
- Enom rejects the API key
- Copy it again with no spaces at either end. Some registrars only show the secret once, so create a new key if you didn't save it.
- Enom rejects calls from Lemon Domains' IP address
- Lemon Domains connects from 2.31.94.66. Add it to the API key's allowed IPs at Enom.
- Some domains are missing
- Make sure the API key belongs to the Enom account (or sub-account) that holds those domains. Connect each account separately.
Rather not use an API key? Import by paste or CSV
Copy your list from the Enom portal, paste it into Lemon Domains, and you're done. Re-import any time to refresh. Paste or CSV import needs no Enom credentials at all.
- 1Open your Enom account at enom.com and go to the domain list.
- 2If the list paginates, switch to "show all" or the largest page size so every Enom domain is visible.
- 3Copy the visible list, or export to CSV if Enom offers it from the account area.
- 4In Lemon Domains, click Import, paste the list or upload the CSV, and map the columns. Lemon Domains previews everything before it commits.
- 5Give the registrar account a friendly label (for example "Enom personal" or "Enom client work") so sub-accounts stay distinct.
