Custom domain name
You can attach a custom domain name to an API served via Nadles API Gateway, so that, instead of the domain name assigned to your API by Nadles (like https://<subdomain>.p.nadles.com/
), users access your API via the domain name owned by you.
Warning
In order to successfully complete the setup, you must be able to edit DNS records of the domain name.
Setting up a custom domain name¶
To start, navigate to APIs → choose an API → API Settings.
Scroll the page down to the Custom domain name section.
Here, enter the domain name you'd like to use for your API.
By clicking "Submit" you initiate a domain ownership verification process.
Ownership verification¶
To verify ownership, you need to add two DNS records.
- a TXT record for the base domain with a unique value generated by Nadles
- a CNAME record for the desired subdomain referencing the Nadles API Gateway's domain name,
p.nadles.com
.
In this example we're attaching api.myfirstapi.com
, so the two records to add to myfirstapi.com
are:
Type: TXT
Name: @
TTL: 3600
Text Data: nadles_verification_8KcfbFwYGieHpqTY8kVmGA.wD8tvwHe3YyVgG9WScYFfM
After you've added the records, click on the "Check DNS propagation status" and make sure that the records have propagated to the most servers.
Then click "Verify DNS records" to make Nadles verify the ownership and issue a SSL certificate.
Once the SSL certificate is issued, the status is updated:
And your custom domain name is displayed everywhere instead of the standard access URL assigned by Nadles:
Path prefix¶
If you plan to use the same domain name for several APIs, you need to specify the path prefix.
In case several APIs are configured to be served on the same domain name, Nadles API Gateway, just like many other API Gateways, will use the path prefix to distinguish between them.
Example
Let's say you plan to set up Weather API and Currency API with Nadles on the same domain name api.myapi.com
.
You'll have to set different path prefixes for them in the Custom domain name section.
For Weather API:
When the user makes a call to https://api.myapi.com/weather/current.json
, the request is forwarded to Weather API.
For currency API:
If the user makes a call to https://api.myapi.com/currency/eur/usd
, the request is proxied to Currency API.
The path prefix is stripped from the request URL before Nadles proxies the request to your API backend.
Example
If Weather API from the previous example has a base URL
https://weather.execute-api.eu-central.amazonaws.com/
,
then the request
GET https://api.myapi.com/weather/current.json
is actually proxied to the backend as
GET https://weather.execute-api.eu-central.amazonaws.com/current.json
Note that the /weather
part was removed from the request URL.
SSL certificate¶
Once the domain ownership verification succeeds, Nadles issues an SSL certificate for the domain name. The process is automatic and can take up to 10 minutes.
Once that's done, the new URL starts being displayed everywhere: on the checkout page, in the self-service portal, etc.
Nadles takes care of renewing the certificate when it approaches the expiration date.
