Authentication

{{% cloud %}} InfluxDB Cloud requires all query and write requests to be authenticated using InfluxDB authentication tokens. {{% /cloud %}}

Use InfluxDB authentication tokens with the following authentication schemes:

• Authenticate with the Token scheme
• Authenticate with a username and password scheme

Authenticate with the Token scheme

Token authentication requires the following credential:

• token: InfluxDB authentication token

Use the Authorization header with the Token scheme to provide your token to InfluxDB.

Syntax

Authorization: Token <token>

Example

{{< code-tabs-wrapper >}} {{% code-tabs %}} curl Node.js {{% /code-tabs %}} {{% code-tab-content %}}

{{% get-shared-text "api/v1-compat/auth/oss/token-auth.sh" %}}

{{% /code-tab-content %}} {{% code-tab-content %}}

{{% get-shared-text "api/v1-compat/auth/oss/token-auth.js" %}}

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

Authenticate with a username and password scheme

Use the following schemes with clients that support the InfluxDB 1.x convention of username and password (that don't support the Authorization: Token scheme):

• Basic authentication
• Query string authentication

Manage credentials

Username and password schemes require the following credentials:

• username: InfluxDB Cloud username
• password: InfluxDB Cloud authentication token

Basic authentication

Use the Authorization header with the Basic scheme to provide username and password credentials to InfluxDB.

{{% api/v1-compat/basic-auth-syntax %}}

Syntax

Authorization: Basic <username>:<password>

Example

{{< code-tabs-wrapper >}} {{% code-tabs %}} curl Node.js {{% /code-tabs %}} {{% code-tab-content %}}

{{% get-shared-text "api/v1-compat/auth/oss/basic-auth.sh" %}}

{{% /code-tab-content %}} {{% code-tab-content %}}

{{% get-shared-text "api/v1-compat/auth/cloud/basic-auth.js" %}}

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

Query string authentication

Use InfluxDB 1.x API parameters to provide username and password credentials through the query string.

{{% note %}}

Consider when using query string parameters

• URL-encode query parameters that may contain whitespace or other special characters.
• Be aware of the risks when exposing sensitive data through URLs. {{% /note %}}

Syntax

 /query/?u=<username>&p=<password>
 /write/?u=<username>&p=<password>

Example

{{< code-tabs-wrapper >}} {{% code-tabs %}} curl Node.js {{% /code-tabs %}} {{% code-tab-content %}}

{{% get-shared-text "api/v1-compat/auth/oss/querystring-auth.sh" %}}

{{% /code-tab-content %}} {{% code-tab-content %}}

{{% get-shared-text "api/v1-compat/auth/oss/querystring-auth.js" %}}

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

InfluxQL support

The compatibility API supports InfluxQL, with the following caveats:

• The INTO clause (e.g. SELECT ... INTO ...) is not supported.
• With the exception of [DELETE](/{{< latest "influxdb" "v1" >}}/query_language/manage-database/#delete-series-with-delete) and [DROP MEASUREMENT](/{{< latest "influxdb" "v1" >}}/query_language/manage-database/#delete-measurements-with-drop-measurement) queries, which are still allowed, InfluxQL database management commands are not supported.
