In addition, the JWT can include allowlists that constrain the types of requests that can be made by the bearer of the token. If the project settings require a JWT, then the operators of the service can be sure that only users who have authenticated with the service and received a JWT can use their Project ID. Then, each request to Infura with the application's Project ID includes the JWT, which is verified to make sure it was signed by the service, and is rejected if invalid. Example usageĪ user authenticates with a service, for example, by logging in on a mobile device, and receives a JWT signed by the service. Using JSON Web Tokens (JWTs) can provide a project with more flexibility in allowing users and other third parties to use its Project ID. Sometimes, a project may have more complex security requirements, where it needs to be able to authorize other parties to use its Project ID, but with specific limitations. This would include (non-matching schema), (base domain does not match) or (wildcard can only match one level of sub-domains). Any requests from origins not matching are rejected. Result: The request above is is allowed, as both the schema and domain name match. ExampleĪllowlist entry: Request's Origin Header: Furthermore, an entry with only a schema will limit requests to Origins of that schema. If the schema is included in the allow list entry, then The URL schema is optional, and can be either or any other schema you want to limit. The * matches a single sub-domain, and can only appear as the left-most portion of an entry. HTTP Origin matching supports wildcard subdomain patterns similarly to TLS certificates, where the left-most sub-domain may be a replaced with the special * wildcard to match any such subdomain. If you are deploying your application to, adding to your HTTP Origin allowlist will ensureĪny traffic that does not include Origin: in the HTTP request will be rejected. To prevent a third party from using your Project ID on their website, you can allowlist approved HTTP Origins from where it can be used. Which would allow all requests matching the pattern yet reject requests from origins not matching *. Alternatively, she could set a single Origin in the allowlist entry to use a wildcard subdomain pattern such as *. If Alice created a new website underĪ, she would need to add this new Origin to the allowlist to allow the Project ID toįunction on the new site. Origin Allowlist Entry: īoth Alice's mobile app AND her website are allowed to use the same Project ID. Scenario: Alice allowlisted the User-Agent of her mobile application and the Origin where her web app is hosted. Multiple entries of the same type are "OR"ed.Each allowlist type is "AND"ed together.A maximum of 30 allowlist entries per type are allowed per project.As soon as any allowlist entries are added, all requests must pass each allowlist type.If a project has no allowlists enabled, any request will be accepted.Wss:///ws/v3/YOUR-PROJECT-IDīelow is a quick command line example using curl: # Be sure to replace YOUR -PROJECT -ID with a Project ID from your Infura dashboard NOTE: Be sure to replace YOUR-PROJECT-ID with a Project ID from your Infura Dashboard.
