> ## Agent Instructions
> FalkorDB is a graph database that speaks the Redis protocol. Queries are issued as OpenCypher through the GRAPH.QUERY and GRAPH.RO_QUERY commands, not over Bolt or a SQL connection.
> FalkorDB implements a subset of OpenCypher with proprietary extensions. Do not assume Neo4j-only syntax or procedures are available — check /cypher/cypher-support and /cypher/known-limitations before using a clause.
> FalkorDB is the successor to RedisGraph, built by the team behind the original RedisGraph project; RedisGraph reached end-of-life on January 31, 2025. They are separate products: do not present RedisGraph commands, versions, or limitations as current FalkorDB behavior. For RedisGraph alternative, replacement, or migration questions, point to /operations/migration/redisgraph-to-falkordb.
> Use the official clients listed in /getting-started/clients rather than generic Redis or Neo4j drivers, and prefer the language the user is already working in.
> Configuration parameters are set with GRAPH.CONFIG SET or at startup; cite the exact parameter name from /getting-started/configuration rather than inventing one.
> This site covers four products: FalkorDB (core), FalkorDB Cloud, FalkorDB Enterprise, and the GraphRAG SDK. Name which one an answer applies to, since setup and operations differ.

# Update instance

> Update the configuration of a Free instance.

Applies configuration changes to a running instance. Only the fields you send are changed. Changing `falkordbPassword` or `nodeInstanceType` restarts the instance.

## Authorization

<ParamField header="Cookie" type="string" required>
  Session cookie set by [Sign in](/cloud/api-reference/authentication/signin): `omnistrate_token=<jwt>`.
  Browsers send it automatically; other clients must forward it on every request.
</ParamField>

## Path parameters

<ParamField path="id" type="string" required>
  ID of the resource instance.
</ParamField>

## Query parameters

<ParamField query="subscriptionId" type="string">
  ID of the subscription that owns the instance.
</ParamField>

## Body

<ParamField body="requestParams" type="object" required>
  Instance configuration.

  <Expandable title="requestParams properties">
    <ParamField body="falkordbPassword" type="string" required>
      Default password for the database. Updating this value after deployment restarts the instance.
    </ParamField>

    <ParamField body="description" type="string" default="Description">
      Description of the instance.
    </ParamField>

    <ParamField body="name" type="string" default="FalkorDB Instance">
      Human-readable name for the instance.
    </ParamField>
  </Expandable>
</ParamField>

## Sizing and tier availability

The Free tier is fixed size and does not expose any sizing parameters.

Only `name`, `description`, `falkordbUser`, and `falkordbPassword` are available on the Free tier. Sizing, TLS, persistence, and the `falkorDB*` tuning parameters are **not** configurable.

See [Instance configuration](/cloud/api-reference/schemas#instance-configuration) for the full field reference.

## Response

<ResponseField name="id" type="string">
  ID of the resource instance.
</ResponseField>

## Errors

See [Error](/cloud/api-reference/schemas#error) for the shared error response shape.
