The Independent Popular Action (Spanish: Acción Popular Independiente, API) was a Chilean political party, created on 27 April 1968,[1] intended to be part of the Popular Unity and support the candidacy of Salvador Allende in the presidential election of 1970.

In the case of API, it was an organization that brought together left-wing independent elements, and less revolutionary than the MAPU and the MIR.

The party joined the moderate wing of the UP, maintaining a critical position.

The same situation was repeated for all parties that made up the Popular Unity.

[3] API President Rafael Tarud, went into exile, and in 1987 was one of the founders of the Party for Democracy (PPD).
