# Consul Intention Check
|
|
|
|
Command: `consul intention check`
|
|
|
|
Corresponding HTTP API Endpoint: [\[GET\] /v1/connect/intentions/check](/api-docs/connect/intentions#check-intention-result)
|
|
|
|
The `intention check` command checks whether a connection attempt between
|
|
two services would be authorized given the current set of intentions and
|
|
Consul configuration.
|
|
|
|
This command requires less ACL permissions than other intention-related
|
|
tasks because no information about the intention is revealed. Therefore,
|
|
callers only need to have `service:read` access for the destination. Richer
|
|
commands like [match](/commands/intention/match) require full
|
|
intention read permissions and don't evaluate the result.
|
|
|
|
-> **Note:** This command will always treat intentions with `Permissions`
|
|
defined as _deny_ intentions during evaluation, as this endpoint is only suited
|
|
for networking layer 4 (e.g. TCP) integration.
|
|
|
|
The table below shows this command's [required ACLs](/api-docs#authentication). Configuration of
|
|
[blocking queries](/api-docs/features/blocking) and [agent caching](/api-docs/features/caching)
|
|
are not supported from commands, but may be from the corresponding HTTP endpoint.
