Hello, we have built a chart that can show graphs about some data from client companies.
We need a way to only show the respective data to the right companie, we have thinked about using a psot or get parameter to use as a filter to make the query show the data, but this has security problems, since they can access data from other companie if change the parameter, how can we ensure that a companie cannot acess data from another companie ?
Can you guys show the direction?

Thank you.
