How to create a TripAdvisor API key on Terra, their developer platform, so you can refresh reviews more often and add more sources.
Would you like your TripAdvisor reviews to refresh more often, or to display more TripAdvisor sources?
In this guide, we’ll show you when you need a TripAdvisor API key. We’ll also cover how to create one on Terra, TripAdvisor’s developer platform, and how to add or remove it in Reviews Feed. If you decide to use your own key, all you need is a Terra account, which is separate from any TripAdvisor account you already have.
Requirements: TripAdvisor feeds require the Elite license level of Reviews Feed.
Before you get started, make sure the latest version of Reviews Feed is installed and activated on your WordPress site.

Do You Need a TripAdvisor API Key?
An API key is optional. Your TripAdvisor feeds work without one.
Without a key, Reviews Feed connects to TripAdvisor for you. In that case, your TripAdvisor reviews refresh once a week. Your site can also hold up to three TripAdvisor sources without a key.
Adding your own key changes two things:
- Faster updates: your TripAdvisor reviews refresh every 12 hours instead of once a week.
- More sources: you can add more than three TripAdvisor sources.
When you try to add a fourth TripAdvisor source without a key, Reviews Feed shows the message Source Limit Exceeded. Please enter API Key. It then takes you back to the step where you can add a key.
If the weekly refresh suits your site and you display three or fewer TripAdvisor sources, you don’t need a key at all.
Adding a TripAdvisor Source Without a Key
To get started, we’ll connect TripAdvisor as a new review source without an API key.
When you add a TripAdvisor source, Reviews Feed asks for an API key first. If you don’t have one, you can skip this step.
On the Add an API Key for TripAdvisor step, leave the field empty. Then, click Skip.
Next, paste the link to the business’s page on TripAdvisor into the Page URL field. Then, click Finish.
Reviews Feed adds the source and shows Source added successfully.
The Page URL field accepts three kinds of input:
- The link to a hotel, restaurant, or attraction page on TripAdvisor. These links contain “-d” followed by numbers.
- The link to one review of the business. Reviews Feed adds the business the review belongs to.
- The numeric location ID on its own. This is the number that follows “-d” in the page’s link.
Reviews Feed needs a link to a single business. When you paste a link to something else, a message under the field tells you what the link points to:
- Tours and experiences: these links lead to Viator, which isn’t available through TripAdvisor’s public API.
- Member profiles: these links lead to a TripAdvisor member, not a business.
- Category pages: these links lead to a destination or a list of places, not a single listing.
If you see one of these messages, or one saying Reviews Feed couldn’t find a TripAdvisor location ID, open the business’s own page on TripAdvisor. Then, copy its link and paste it into the field. Our guide on adding a TripAdvisor source lists the links Reviews Feed accepts and what each message means.
Creating Your Terra API Key
If you’d like faster updates or more sources, you’ll need your own key. TripAdvisor issues API keys through Terra, its developer platform.
Terra uses its own account, separate from any TripAdvisor account you have for your business. Keys and accounts from TripAdvisor’s older Content API don’t carry over to Terra. You’ll need a new Terra key even if you used a TripAdvisor API key before.
First, go to TripAdvisor’s developer page and sign up for Terra Discover, the package that replaced the Content API. Terra’s FAQ covers the sign-up.
Discover is pay-as-you-go. It includes a complimentary tier. Usage beyond that tier is billed. Terra’s usage-based pricing page lists the current prices.
Once you’ve signed up, generate your API key from the Terra Dashboard. Then, open the Overview tab to find your key on the My API Key card. Since you’ll need it on your WordPress site in a moment, copy it.
Note: Treat your API key like a password and don’t share it publicly. If it’s ever exposed, regenerate it from the My API Key card. Then, add the new key to Reviews Feed. Terra’s security guide explains that regenerating revokes the old key right away.
That’s everything you need from Terra. Next, head back to your WordPress site.
Adding the Key to Reviews Feed
With your Terra key copied, you’re ready to save it in Reviews Feed.
In your WordPress dashboard, go to Reviews Feed » Settings.
On the General tab, scroll down to the Manage API Keys section. Then, click the pencil icon on the TripAdvisor card.
In the window that opens, paste your key into the field. Then, click Update to save it.
The button in this window reads Add until you enter a key. It changes to Update as soon as you do.
Reviews Feed checks the key as you save it. If the key doesn’t work, Reviews Feed doesn’t save it and asks you to check the details you entered.
In that case, copy the key from the Terra Dashboard again. Then, paste it into the field.
Once the key is saved, your TripAdvisor reviews refresh every 12 hours. You can also add more than three TripAdvisor sources.
The same key covers every TripAdvisor source in the plugin. You won’t need to enter it again for each source you add.
Your Google and Yelp keys go in the same place, as the Manage API Keys section of our settings reference shows.
Removing an API Key
If you no longer want to use your own key, you can remove it at any time. Reviews Feed then switches back to the connection built into the plugin.
Removing a key is also the fix for a key from TripAdvisor’s older Content API. TripAdvisor retired that API on August 31, 2026. Those keys no longer work.
If one of those keys is still saved and you display TripAdvisor sources, Reviews Feed shows a notice on the Settings page. To jump to your keys from there, click Manage API Keys in the notice.
You can tell the two kinds of keys apart by their shape. Content API keys are 32 characters with no hyphens. Terra keys are longer and contain hyphens.
Next, open the TripAdvisor key window from the Manage API Keys section, the same way you did when adding the key. In the window, click Remove.
Reviews Feed removes the key. The notice no longer shows. Your TripAdvisor reviews now refresh once a week.
If you’d like to keep using your own key, add a Terra key in place of the old one instead. The steps are the same as in Adding the Key to Reviews Feed.
That’s it! You now know when you need a TripAdvisor API key, how to create one on Terra, and how to add or remove it. Next, check out our guide on displaying your reviews feed to make the most of the reviews on your site.
Frequently Asked Questions
Below, we’ve answered some of the most common questions about TripAdvisor API keys in Reviews Feed.
Do I need a TripAdvisor API key to display TripAdvisor reviews?
No. Your TripAdvisor feeds work without a key.
See the Do You Need a TripAdvisor API Key? section above for what a key changes.
Why can’t I add another TripAdvisor source?
The message “Source Limit Exceeded. Please enter API Key.” means your site already has three TripAdvisor sources without a key. To add more, create a Terra API key. Then, add it to Reviews Feed.
Why does Reviews Feed say my TripAdvisor API key has stopped working?
Your saved key comes from TripAdvisor’s older Content API, which TripAdvisor retired on August 31, 2026. Those keys don’t carry over to Terra. You can remove the key to use the connection built into the plugin. You can also replace it with a Terra key.
How can I tell if my key is a Content API key or a Terra key?
You can tell by its shape. Content API keys are 32 characters with no hyphens. Terra keys are longer and contain hyphens.
Which TripAdvisor links can I use as a source?
In the Page URL field, use the link to a hotel, restaurant, or attraction page, which contains “-d” followed by numbers. You can also enter that number on its own. If your link points to a tour, a member profile, or a category page, open the business’s own TripAdvisor page and copy that link instead.
Do I have to pay for a Terra API key?
Terra Discover is pay-as-you-go, with a complimentary tier. Usage beyond that tier is billed. You’ll find the current prices on Terra’s usage-based pricing page.
Why didn’t Reviews Feed save my key?
Reviews Feed checks the key when you save it and doesn’t save a key that doesn’t work. If the key wasn’t saved, copy it again from the Terra Dashboard. If you regenerated your key on Terra, the old one no longer works. In that case, paste the new one instead.
