# Variables

## GET flow variables

<mark style="color:blue;">`GET`</mark> `https://api.appmixer.com/variables/:flowId`

Get variables.  Variables are placeholders that can be used in component config or inputs. These placeholders are replaced either at runtime by data coming from components connected back in the chain (dynamic variables) or by real values (static variables).\
\
Get component config variables:\
\
`curl "https://api.appmixer.com/variables/93198d48-e680-49bb-855c-58c2c11d1857?componentId=e25dc901-f92a-46a2-8d29-2573d4ad65e5" -H "Authorization: Bearer [ACCESS_TOKEN]"`\
\
\
Get component input variables:\
\
\&#xNAN;*In this case, we identify the connection (one path in the flow graph) by source and target components,  output port of the source component and input port of the target component. This address uniquely identifies one "link" in the flow graph.*\
\
`curl "https://api.appmixer.com/variables/93198d48-e680-49bb-855c-58c2c11d1857?srcComponentId=ba09820f-db59-4739-b22d-414826842495&srcComponentOut=trigger&tgtComponentId=e25dc901-f92a-46a2-8d29-2573d4ad65e5&tgtComponentIn=message" -H "Authorization: Bearer [ACCESS_TOKEN]"`
